FOLDING HARROW.

Application filed January 27, 1912.

Specification of Letters latent.

Patented July 23, 1912.

Serial No. 673,840.

To all whom it may concern Be it known that I, KIRK HILLIARD, a citizenof the United States, residing at Vinton, in the county of Benton andState of Iowa, have invented certain new and useful Improvements inFolding Harrows, of which the following is a specification, ref erencebeing had therein to the accompanying drawing. a

This invention relates to harrows and has for its object the productionof an efficient harrow beam whereby a number of harrow frames may beattached to the beam in such a manner as to allow the harrow frames andbeam to be folded in a compact position.

Another object of this invention is the production of an eflicient hingestructure for engaging the harrow beam sections.

With these and other objects in view, the

invention consists in general of certain novel constructions,arrangements and combinations of parts as will be hereinafter fullydescribed, illustrated in the accompanying drawings, and specificallyclaimed.

- In the accompanying drawings :Figure 1 is a top plan view of theharrow. Fig. 2 is a perspective view of the harrow bar showing the samein its folded condition. Fig. 3 is a longitudinal section of a portionof the harrow bar showing the manner of engaging the hinge thereto. Fig.4: is a detailed perspective of the socket plate. Fig. 5 is a detailperspective of the hinge plate.

Referring to the drawings by numerals 1 designates the primary portionof the harrow beam which carries at each end a socket plate 2. Each ofthese socket plates comprises a channel member straddling the beam asillustrated in Fig. 2. The socket plate 2 is provided with a pluralityof upwardly extending ears 3 at one end and also carries near the centerthereof upon its flanges an upwardly extending ear 4:. The

socket plate 2 is fixedly secured to the ends of the primary beam 1through the medium of bolts or pins 5 which pass through the apertures 6formed in the plate 2. This plate 2 only extends for approximately halfits length upon the beam 1, the other half being left to receive theadjacent ends of the auxiliary sections 7 of the beam. A hinged plate 8is carried by the inner ends of the auxiliary sections 7 of the beam andthis hinge plate comprises a flat body portion having rolled ends 9. Apin 10 passes through the apertured ears 4 of the plate 2 and acts as apintle for the hinge plate 8. l/Vhen the auxiliary section 7 is placedin an operative position, that is to say, hav- 1ng lts lnner end placedwithin the socket plate 2, a pin llis passed through the opposlte rolledportion 9 and through the pivot ears of the plate 2, thereby holding theauxillary section 7 in a horizontal position.

Of course, when it is so desired to fold the auxiliary sections upon theprimary sec tion the pin 11 is withdrawn from the ears 3 and theauxiliary sections 7 may be folded to the position as illustrated inFig. 2. Eyes 12 are carried by each of the auxillary and primarysections, and to these eyes are connected harrow frames 13 which may beof any desired construction. Draft links 14 are connected to the frontof the harrow beam and have their inner ends connected to the primaryand auxiliary sections of the beam so as to allow the beam to be readilyfolded without interfering with the operation of the draft links.

In view of the fact that the harrow beam may be folded in the manner asabove described it will be obvious that the harrow may be adjusted inwidth by swinging the auxiliary end portions back upon the primaryportion of the beam when the harrow is desired to be used in narrowplaces. It will be further-obvious that in View of the fact that theinner end of the auxiliary section is placed within the side walls ofthe channel member 2, the auxiliary portion will be held against lateralswinging relative to the primary section of the beam.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

What is claimed is 1. A folding harrow beam comprising a primary portionand a plurality of auxiliary portions, socket plates carried by saidprimary portion, a hinged plate carried by each of the auxiliaryportions, means for hingedly securing said plates to said socket plates,and means engaging said hinge plate and socket plate for holding saidauxiliary portions of said harrow beam in an operative position.

2. A harrow of the class described comprising a beam, said beamcomprising a plurality of sections, socket plates carried by one of saidsections, hinge plates carried by the other of said sections, means forhingedly securing said hinge plates to said socket plates, and lockingmeans carried by said hinge plate and engaging said socket plates forholding said other sections in their sections, ears carried by saidsocket plates, 8. A socket plate for a sectional harrow,

horizontal position.

beam comprising a substantially U-shaped body portion, ears formed uponsaid body portion near one end, intermediate ears carried by said bodyportion, said ears being adapted to be engaged by means for securing aharroW beam thereto.

4. A foldable harrow beam comprising a primary section, and a pluralityof auxiliary sections, socket plates carried by the ends of said primarysection, hinge plates carried by the inner ends of said auxiliarysections, said hinge plates comprising a substantially U-shaped body andstraddling said and means passing through said roll portion of saidhinge plates for hingedly securing said sections together, and means forholding said auxiliary sections in said socket plate.

In testimony whereof I hereunto aflix my signature in presence of twoWitnesses.
